Post From: IBKR claims Deprecated TWS API version

Evening all
20251205 upddate:
Sierra/TWS worked correctly today for position display and order management

As for questions from John SC Support about Message logs:

-Trading message from IB: Order Canceled - reason:. Error Code: 202. ServiceOrderID: 31295. InternalOrderID: 35970.
This was likely a race condition where I attempted to place a Stop-limit order for Entry and the market was away from that price at arrival. Human error. You can also get this error if: Order price is too far away from current market price, and order was manually cancelled by the user or an OCO function, avoidance of self trading, some other order parameter was invalid

-Trading message from IB: Order Event Warning:Attribute 'Outside Regular Trading Hours' is ignored based on the order type and destination. PlaceOrder is now being processed. Error Code: 2109. ServiceOrderID: 31293. InternalOrderID: 35963.

Little was gained for feedback from IBKR support. I gave them logs from today and yesterday and they just kept repeating that the CME hours in the system are 0930-1600 EST and 1800-1700 EST. DAY orders will cancel at 1700 EST. I would note that today's message log had no instances of this message. So perhaps the change in API version cleaned this up.

-Message from IB: Market data farm connection is OK:usfarm.nj. IB Error Code: 2104. Request ID: -1.

Response was "normal situation as API pings for connections the user is not employing. Weird answer but I moved on.
